With the ongoing need for miniaturized systems in many biological and chemical applications, there is an increasing demand for the development of versatile methods for controllable transport and manipulation of small volumes of liquids. [ 1–9 ] Recently, liquid marbles — liquid droplets encapsulated by self-organized hydrophobic particles at the liquid/air interface — have been revealed as a ne...

The formation of highly uniform charged molten metal droplets from capillary stream breakup has recently attracted significant industrial and academic interest for applications requiring high-speed and high-precision deposition of molten metal droplets such as direct write technologies. Exploitation of the high droplet production rates intrinsic to the phenomenon of capillary stream break-up an...

Electrospray thrusters work by extracting ions or charged droplets directly from a liquid surface using an electrostatic field and accelerating them in that field to produce thrust [1]. This method could lead to more efficient and precise thrusters for space propulsion applications. Emission occurs from sharp emitter tips, which enhance the electric field and constrain the emission location. Th...

Lipid droplets ensure their own consumption H ungry yeast cells use a clever form of recycling to ensure that they can keep consuming stored lipids, Wang et al. show. Lean times spur yeast cells to enter a quiescent state known as the stationary phase. They break down cached lipids by delivering lipid droplets to the vacuole and resort to autophagy, in which they digest a portion of their own c...

PDLCs consist of liquid crystal droplets that are dispersed in a solid polymer matrix. The resulting material is a sort of "swiss cheese" polymer with liquid crystal droplets filling in the holes. These tiny droplets (a few microns across for practical applications) are responsible for the unique behavior of the material. By changing the orientation of the liquid crystal molecules with an elect...

many isotropic oils, this liquid crystal is not soluble in water. We therefore We have prepared monodisperse suspensions of nematic liquid use an ionic surfactant, sodium dodecyl sulfate (SDS), to stabilize the crystal droplets in water. The droplets are stabilized by polyvinyl droplets. This allows us to use standard fractionated crystallization methods alcohol, a polymer that induces planar a...

INTRODUCTION The superheated drop detector (SDD) is composed of droplets of a sensitive liquid with low-boiling point and a medium supporting the droplets dispersed throughout the medium. The SDD has been mainly used for neutron dosimetry and recently also for γ -rays. However the conditions of bubble formation have been discussed for neutrons but there have been a little works for gamma-rays. ...

We analyzed the behavior of sessile ferroelectric liquid droplets in vicinity a pyroelectrically charged crystal, an experimental configuration that allows testing recently observed coupling between polarizations fluid and solid materials, conditions no direct contact. Results demonstrate polarizations’ also exists this has two distinct effects. Specifically, it gives rise both to electromechan...

The effective transfer of tiny liquid droplets is vital for a number of processes such as chemical and biological microassays. Inspired by the tarsi of meniscus-climbing insects, which can climb menisci by deforming the water/air interface, we developed a mechano-regulated surface consisting of a background mesh and a movable microfibre array with contrastive wettability. The adhesion of this m...
